Read the following text. 101. People worldwide are living longer. Today most people can expect to live into their sixties and beyond.Everycountry in the world is experiencing growth in both the size and the proportion of older people in the population.By 2030, 1 in 6 people in the world will be aged 60 years or over- the share of this group will increase from 1billion in 2020 to 1.4 billion and by 2050, the world’s population of people aged 60 years and older will be 2.1billion. The number of persons aged 80 years or older is expected totriple between 2020 and 2050 to reach 426million.2. While this shift in distribution of a country’s population towards older ages-known as population ageing-startedin high-income countries (for example in Japan 30% of the population is already over 60 years old), it is nowlow- and middle-income countries that are experiencing the greatest change. By 2050, two-thirds of the world’spopulation over 60 years will live in low- and middle-income countries.3. By income group, the sharpest growth in the numbers of older people will occur in countries currently classifiedas middle income. This is unsurprising, as these countries make up 74 per cent of the world’spopulation. What’ssurprising is that these numbers are increasing at a much faster rate than in either lowor high-income countries.4. Population aging is sounding alarms worldwide. The older people will have to spend their investmentsto supportthemselves pulling money from the economy. Another issue is fiscal stress. Government treasuries will bestrained by rising pension liabilities, the cost of health and long-term care associated with the expected growthin the incidence of chronic diseases such as diabetes, heart ailments, dementia,cancer, among others.5. Various responses could cushion the economic burden of population aging. These include policy reforms topromote the health and pension financing of the old. Raising the legal age of retirement, which has been relativelystable in nearly all countries for the past several decades would also ease the burden. Additionalapproaches includeefforts to increase health systems’ emphasis on early detection and on prevention of disease through, for example,better awareness of the benefits of physical activity and subsidization of such activity. Relaxing the institutionaland economic barriers to international immigration from regionswith relatively large working-age populationscould alleviate labour shortages.Answer the following questions, based on the passage above.i. Complete the following analogy appropriately, based on your understanding of paragraphs 1 and 2.From the passage, we can infer that the dynamics of greying population shifting from high-income to low andmiddle-income countries, is comparable with the regular oscillation .ii. Fill in the blanks with the appropriate option from those given in brackets, based on your understanding ofparagraph 2. 1The population researchers say that it is unsurprising that the middle-income countries will see the sharpestgrowth in the numbers of older people because these countries currently make up 74 percent of the worldpopulation is .......... (a fact! opinion) because it is.................................... (a/an subjective judgement! objectivedetail ).iii. With vast numbers of greying population inundating the world, the effects on the economies of the countrieswould be devastating. How could this situation be tackled? Answer in about 40 words. 2iv. List any two examples of ‘cushioning economic burdens’ as referred to, in Paragraph 5. 1v. The rate of growth of size and the proportion of older persons in the population has gone up for every countryin the world. 1State any one inference that can be drawn from this based on information in paragraph 1
